How do I update the firmware of my SMT, SMX, SMC, SRT, XP, or XU series Smart-UPS?

Published date: 16 January 2020


Next generation Smart-UPS products feature user upgradeable UPS Firmware.
This allows for ongoing improvements and feature enhancements of Smart-UPS products after deployment.

Product line:

Smart-UPS SMT, SMX, SMC, and SRT Families, as well as the XP1K9NN42RCC and XU1K3LLXXRCC Industrial Smart-UPS products


Since we will continually release new products that are supported by the tool, we identify devices that are NOT supported.

Devices that do *NOT* have upgradable firmware:

  • Legacy Devices:  Models beginning with: SU, SUA, SUM, SURT, SURTD, SURTA, SRC (IE: SUA3000XL, SU2200NET, SURTD3000RMXLT)
  • Next Generation Devices: SMX750, SMX1000, SMX1500 with firmware UPS 02.x or lower.
    • These units are 120 V devices built prior to date code 1037. Date code is the first 4 numbers in your serial number. (IE: Serial Number AS1036123456 Would not be supported.)


There are two methods to update the firmware of the UPS:
  • Locally via a Serial or USB connection using the Firmware Upgrade Wizard application. This is the most reliable method and should be used whenever possible. 
  • Locally via a USB Thumb Drive (XU1K3LLXXRCC Only)
  • Remotely via the Network Management Card (Requires a Network Management Card
  • Remotely via the APC SmartConnect Cloud (Models with a "C" suffix only  - IE: SMT1500C)
Firmware Upgrade Wizard and Network Management Card requires that your turn off the output power of the UPS. 
If you are updating via the Network Management Card, you must ensure that your network access is not dependent on the UPS for power.
